To allwkomz'tmay cancer-n; I

Be itknown that I ELBY A. Monms, a citizen of the United States,residing at Leetonia, in the county of Columbiana and State of Ohio,have invented certain new;

and useful Improvements in Trolley-Retrievers, of which the Y followingis fa specification. I Y

. This invention devices for electric railway cars, and moreparticularly to a novel improvement in jtrol ley retrievers;

novel trolley pole and stand, of such construction that when the poleleaves the usual conductor wire andjumps upwardly, it-will.

be automatically returned to a safety position, thus preventing thepolefrom striking the feed wire supports or pole causing consequent damage.s 1

A further object of, the inventioni isto provide .a simple and reliableconstruction.

inafter more fullyillustrated and claimed.

A preferred and 'practical embodiment of the invention is shown in the:accompanying drawings, in which l V Figurel is a vertical sectional viewshowing the-general arrangement and structural details of myimproveddevice the same be.- ing in its normal conditionj Fig. 2 is aview similar to Fig 1, but showing the relative position of the; trolleypole after it leaves the conductor wireflin full lines, andindicatingthe safety position to which the same automatically falls, indotted lines. ,I

Fig. 3 is a top plan view of the invention; Similar references designatecorrespond.- ing parts throughout the several. figures of the drawings.I, 7 In carrying out the. present invention; it is proposed to'provide abase plate 1 of suitable dimensions, which may be readily positioned andsecured upon the top of a car, or other vehicle by suitable fasteningmeans.

relates tooverhead trolley his end, the invention -cohte1np1ates ,a

arms, and.

This baselplate is preferably formed with a relatively large centrallylocated upstand lng bearing boss 2, and a pivot pin 3, which provide apivotal bearing fora trolley pole stand designated generally as S.

As will be observed from Figs; 1 and 2' of the drawings, thetrolleystand S comprlses a frame including 'a' bottom wall 4:

. provided. with a recess 5 in its under side for receiving theupstanding bearing boss 20f the base plate, and also has an opening 6for permitting the pin 3 to project intoan exposed. position to receivea suitable clamping. nut '7, for pivotally holding the ent repframe'ofthe base plate. At thelateral edges of the bottom wall 4 of the frameare provided the upstanding side walls 88,'

which may, for the sake of lightness andeconomy, be of the open orskeleton formation shown, and -provide suitablebearings for the axlebolt 9 of arockable supporting member 10.

As will be observed from *Fig. 3, this supporting-member is preferablyformed at its intern'lediate portion with the hub or oppositely disposedbolt receiving sleeves 11',

while one end thereof is forked as at 12 to pivotally receive one end ofa springguiderod 13. This rod is surroundedby a coiled compressionspring 14, one end-of which abutsagainst the forkedend 12 of thesupporting member 10," while theopposite end thereof abuts against asuitable bracket 15 which 1s secured to'the opposite sidewalls 8 of theframe. For the purpose of holding the end of the springpositivelypositioned in. the bracketxl5, the latter is also preferablyprovided with'the guide pin 16, as will be clearly apparent from. theseveral figures of the drawing. With this arrangement of the spring 14,it will be apparent-that the same will tend to rotate the supportingmember 10 sothat the head portion 17 thereof will have a tendency toswing in a clockwise direction. T 1 a Referring furtlierto thesu'pportingmember 10, it will be observed that therhead portion 17thereof'isprovidedon one side with a hinge knuckle 18, while-theopposite side thereofis provided with the upstanding ears 19 forpivotally receiving therebetween a latchdog .20, which isprovided at oneend with a latch shoulder .21, while its opposite end 22 works againstthe tension of a spring i 22 The hinged knuckle 18 of the support- Itwill thus be understood that the socket element 23 carrying the pole 24is hinged or pivoted tothe supporting member 10, and for the purpose ofmaintaining the longitudinal axes of both the supporting member and thesocket element or trolley pole in alinement, the said socket element isprovided with a keeper shoulder 26 for en gaging with the latch shoulder21 ofthe latching dog 20. As will beuobserved from the drawings,theisocket element 23 is further provided withan offset bracket arm 27',the extremity, ofwhich is connected by means of a spring 28vto asuitable eye carried by the supporting member, as will be observed fromFigs. 1 and 2. This spring has a tendency to swing the entire pole andsocket element 23 .on the hinge 18, which p-' erates to, not onlymaintain a firm engage me'nt "between the shouldersc26 and 21- but alsocompels the pole to drop into a safety position, as will hereinaftermore fully apable abutment member 31,-which is provided with an abutmenthead 32 located directly in the path of movement of the head 17 of thesupporting member 10, whereby the end 22 of the latch dog 20 carriedthereby will engage theisaid head. That is to" say, the yieldableabutment 32 is so arranged with v respect to the supporting member thatwhen" thesame is caused to rotate on it's 7 axis 9 under the influenceof the spring 14,

the end 22 of the latchvv dog will be brought against the head 32 of thetrip device, thereby rocking thelatch dog against the tension of thespring 22 to disengage the latch shoulder 21 of themember 20 from thekeeper shoulder-26 oft'he socket'element;

This trip device is preferably adjustably secured betweenthe arms 88, aswill-be observed from the drawings; To provide for this adjustablemounting, the opposite walls are preferably provided with suitable openings, to permitof therel'ativ'e position of the trip device to bechanged to suit various requirements and conditions, whereby the latchwillbe operated sooner or later within the limit of movement of thesupporting 'member, as circumstances may require,

and, is held in its normal position with respect thereto by means of thelatch dog 20 engaging the keeper shoulder 21. When the parts are in thiscondition, that is when the socket piece is'locked with the supportingmember 10, the entire trolley pole is in its normal useful position, asshown in Fig. 1. In other words, with the socket piece and smppoitiiag:member locked together, the 1 spring 14 exerts its full force on thecoupled members 10 and 28' to hold tlre'trolley wheel-- on the conductorG. I Iowev'er,

gaged from thekeepershou1='der 26, as shown in Fig. 2,-and' the. trolleypole or standard drops to a substantially horizontal safety position,-Fig; 2.

When the trolley pole reachesthe limit of its upward movement and issubstantially vertical, the spring 28 comes into play to positivelyswing the socket element on the hinge1'8' and pull it'toasafety positionwithout relying on the weight of the-"pole as shown by the dotted linesin to bring it down, thereby positively preventing the same fromstrikingany of-the trolley wire supports or cross arms of the trol leyplates. After the latch dog 20' has been released from 'it's"engagement. witlrthe keeper shoulder 26', and the trolley pole is' inits fallen or substantially -horizo'ntal that the pole may be again madeready for use by compressing the spring 14 and rotatingi thesuportingmember 10 on its axis 9- a sufficient-distance to permit the dogto again engage theshoulde'r. Y

safetyposition, it will of course beapparent Without further descriptionit is thought 7 that the many features andladva'ntages ofthe inventionwill .be' readily, understood, and it will of course be apparent thatchanges in the form, proportion and minor details of construction mayberesorted "to without departing; from the spirit-"of the invention orscope 'of the'appe'nded claim;

I claim: V

A trolley" retriever includinga rotatably supported frame "havingopposite side walls, a pole supporting unit consisting of a-pivot'section including an enlarged body portion journaled in the sidewalls ofthe; frame and having oppositely disposed portions one of whichconstitutes a spring abutment while the other carries hinge knuckles,and a pole receiving socket section" also having hinge knuckles forcooperating with the knuckles on'the pivot section to constitute ahinged connection therebetween, a pivoted latch carried by the pivotsection, a-keep'er -on the socket section for cooperating with saidlatch, an offset bracket arm also on the socket section on the sideopposite the keeper, a spring connecting the extremity of the bracketarm with the enlarged portion of the pivot section, a yielding abutmentlocated in the path of movementof the pivoted latch, and a compressionspring arrangedbetween the Walls of the frame and the pivot section.

In testimony whereof I hereunto afiix my signature in the presence oftwo Witnesses.
